Term
protists
Definition
of all the existing organisms, the ones that are most like the earliest, structurally simple eukaryotes; eukaryotic single-celled or simple multicelled organisms that can be heterotrophic or autotrophic and motile or non-motile
Term
predatory/parasitic molds
Definition
group of protists such as slime molds, chytrids, and water molds, that produce spore-bearing structures in their life cycles
Term
protozoans
Definition
term for protists that resemble single-celled heterotrophic protistans that gave rise to animals; animal-like protists
Term
binary fission
Definition
most common type of asexual reproduction in protozoans
Term
plankton
Definition
term for aquatic communities of mostly microscopic organisms which are motile or passive drifters
Term
contractule vacuoles
Definition
organelle used to remove excess water that enters the cell osmotically
Term
sporozoan
Definition
informal name for the parasitic protozoans that complete part of their life cycle inside life cycles inside specific cells of host organisms
Term
malaria
Definition
disease caused by parasitic species of the genus Plasmodiaum
Term
phytoplankton
Definition
term for communities of single-celled aquatic photosynthetic species of algae that are mainly microscopic and drift or swim weakly through the water
Term
algae
Definition
term for protists that are plant-like
Term
euglenoids
Definition
term for flagellated, free-living cells, such as Euglens, that can be autotrophic or heterotrophic
Term
chrystophytes
Definition
term for the mainly photosynthetic, free-living cells such as diatoms, golden algae, and yellow-green algae
Term
dinoflagellates
Definition
term for the mostly photosynthetic, sometimes heterotrophic marine plankton that have cellulose plates and flagella
Term
red tides
Definition
term for the population explosions dinoflagellates in which the water appears red or brown and may contain toxins that kill shellfish, fishes, and fish-eating migratory birds
Term
red algae
Definition
mostly marine algae with phycobilins and other accessory pigments that mask chlorophyll
Term
agar
Definition
gelatinous substance used in bacteriological culture medium that is made from the extracts of cell walls from red algae
Term
euchuma
Definition
extract made from the cell walls of red algae used as a stabalizer in paints, dairy products, and many other emulsions
Term
brown algae
Definition
marine algae that live in cool or temperate waters that contain fucoxanthin pigments and other cartenoids; commonly called kelps
Term
green algae
Definition
algae which contain chlorophylls a and b and are structurally and biochemically most like plants and are their clostest relatives
Term
amoeboid prtozoans
Definition
protozoans such as amoebas, foraminiferans, helizoans, and radiolarians that move by means of pseudopodia
Term
amoebic dysentary
Definition
disease caused by the amoebic parasite Entaamoeba
Term
ciliated protozoans
Definition
protozoans such as paramecia that move by means of cilia
Term
pelicle
Definition
tough but flexible outer covering of certain protozoans such as paramecia
Term
conjugation
Definition
form of sexual reproduction in certain protozoans such as paramecia
Term
macronuclei
Definition
nuclei swapped during this conjugation
Term
animal-like fagellates
Definition
protozoans that move by means of flagella
Term
African sleeping sickness
Definition
disease caused by the flagallated parasite Tyrpanosoma brucei
Term
tsetse fly
Definition
vector that transmits the african sleeping sickness
Term
silicon
Definition
mineral found in the overlapping shells of diatoms
Term
diatomomaceous earth
Definition
deosit of diatoms used in filter, abrasive cleaners, and toothpaste
Term
nori
Definition
a red algal wrapping for rice and fish in sushi bars
Term
algins
Definition
derivative from the cell walls of brown algae used as thickenin, emulsifying, and suspension agents
